A Country of Strangers, a sequel to The Light in the Forest, was published thirteen years later in 1966. In this novel, Richter's protagonist is Stone Girl, who is being returned to her white family.

Reluctant to leave her village and Native American husband, Stone Girl embarks with her son, Otter Boy, on a long, roundabout journey to escape the treaty to return all white captives. At Fort Detroit, her French employer traces her white parents, and she is taken to Pennsylvania against her wishes. She and her son are rejected by her father, Captain Stanton, and subjected to racial prejudice. Stone Girl is wrongly accused of collaborating with the Native Americans to attack the whites, ill-treating her white sister, and stealing. She meets True Son, a recruit of the Twightwee tribe, who helps her to leave the white settlement for the Tuscarawa village.
